Abstract (en)
[origin: WO8102608A1] A fluid injection system for an internal combustion engine such as a spark-ignition engine in which an injection nozzle (22) injects a finely divided spray of fluid, such as water or a water solution, into the engine (10) in response to a flow of atomizing air. The nozzle (22) is connected to a fluid supply reservoir (100) and to the outlet line (28) of an air-injection pump (30) that is connected to an electronic control circuit (32) which includes an inductive pick-up (42a) coupled to the ignition system of the engine and a pressure responsive sensor (48) that is coupled to the intake manifold (14). The electronic circuit (32) thus operates the pump (30) in response to engine speed by virtue of its connection to the ignition system through the inductive pick-up (42a) and in response to engine load by virtue of its connection to the intake manifold (19) through the pressure responsive sensor (48). As a result, the flow of atomizing air to the nozzle (22) and therefore the rate and magnitude of water injection is responsive to engine speed and engine load.
